I've started using (generated) click tracking events as a data source when introducing #FlinkSQL - it's simple, yet still rich enough to let me explain a variety of nice #Flink features.

I've written up a few examples at https://dalelane.co.uk/blog/?p=5806

Flink SQL examples with click tracking events

In this post, I introduce a few core Flink SQL functions using worked examples of processing a stream of click tracking events from a retail website. I find that a practical, real-world (ish) example can help to explain how to use Flink SQL in a way that abstract descriptions, such as processing co

느린 데이터 탐색은 이제 그만, 그랩의 실시간 스트리밍 혁신

그랩은 제플린의 느린 속도와 통합 문제를 해결하기 위해 FlinkSQL 게이트웨이 기반의 새로운 스트리밍 플랫폼을 구축했습니다.
이를 통해 쿼리 응답 시간을 5분에서 1분으로 단축하고, API를 통해 데이터 접근성을 극대화했습니다.

진정한 데이터 민주화는 단순히 쿼리 도구를 제공하는 것을 넘어, 인증, 통합, 배포까지 전 과정을 단순화하는 엔지니어링에서 시작됩니다.

Exploring the Flink SQL Gateway REST API

Using the Flink SQL gateway you can run SQL on your Flink cluster. The REST API is a way to do this programmatically. This article explains how to use it.

💡 Understanding how to install the right dependencies—and troubleshoot things if they go wrong—is an important skill when working with #FlinkSQL.

👉 In his latest blog, @rmoff shares some useful tips and tricks for working with JARs, including how to understand which ones you need and how to check the right one is being used.

New post: "Interesting Stuff - Week 3, 2023".

So, what do we have for Week 3, 2023:

* Support for Plotly in @azuredataexplorer. Very cool!
* Solution to Case 2 in Kusto Detective Agency. The hardest case for me to solve.
* Benefits and challenges of distributed computing. Very good!
* Comparison of SQL-based streaming technologies. Interesting!
* Time support in Flink.

Interesting Stuff - Week 3, 2023

This week we look at cool visualizations in Azure Data Explorer using Plotly. Interesting about benefits and challenges of distributed computing. Comparison of different SQL-based streaming approaches and their use cases, including a look at a streaming database. A really good post about Time in Flink.

Is it only me, or is the support for Docker in Flink really cr*p? Or rather, no "official" images for either the Flink SQL Client or the SQL Gateway.

Sure, you can build it via Dockerfiles, but it is very much hit-and-miss / trial and error. I still haven't managed to build a usable image for the Flink SQL Gateway (based on Flink 1.16).
